Yeah I read it in GracieMag that he did win over Cobrinha in a tourney. Can't remember the details but during that he time he said that he was training morning, afternoon, evening & till the wee hours of the morning & he was literally sleeping on the mats. He says that this was probably why he won over Cobrinha. He also won over Bruno Frazatto at a Brazilian tourney finals (nationals?)...the score was tied & at the last 30 seconds he did an arm drag & he got Frazatto's back. When he started MMA he became overconfident over his ground skills & lost via RNC in an MMA match. He then learned from that experience & resumed training with the gi & has never stopped training with it ever since.
